[0002] After the welding of the car tailgate assembly is completed on the automated line, two employees are required to lift it out of the fixture and transfer it into the corresponding equipment. Taking a mid-sized car as an example, the tailgate assembly weighs 16kg and is nearly 1.5m wide. The ergonomics of manual operation are poor, and quality problems such as bumps and deformation are very likely to occur during the manual lifting, transfer and placement of parts.

[0003] For example, CN111268552B, published on January 14, 2022, discloses a flexible door hanger with hinge fastening, including a hanger frame, an auxiliary fixing device, a contour fixing device, and a pulley support device. In the auxiliary fixing device, a vertical sliding limit mechanism is fixed to the front end of the hanger frame, and the auxiliary fixing mechanism is connected to the front hinge of the door assembly. The auxiliary fixing mechanism is also engaged with the vertical sliding limit mechanism, achieving flexible lifting of the front end of the door. In the contour fixing device, a horizontal sliding limit mechanism is fixed to the hanger frame corresponding to the rear end of the door assembly, and the rear end of the contour fixing component is fixedly connected to the horizontal sliding limit mechanism. The front end of the contour fixing component is engaged with the outer edge of the rear end of the door assembly, achieving flexible lifting of the front end of the door. The bottom support of the door assembly is installed on the pulley support device located at the bottom of the hanger frame. The aforementioned door hanger cannot easily transport a rear door placed on a clamp, resulting in poor practicality. Summary of the Invention

[0024] In use, the back door on the clamp is clamped onto the fixed frame 10 by the clamping assembly. The flipping assembly on the boom 1 and the handle 4 causes the connecting seat 5 to flip, which in turn causes the fixed frame 10 and the back door connected to the connecting seat 5 to flip, so that the back door can be flipped and moved off the clamp, thereby lifting and moving the boom 1. The back door can be finely adjusted by the handle 4, so that the back door on the clamp can be moved conveniently and quickly, making it more practical.

[0025] The flipping assembly includes a rotating base 6 fixedly connected to the connecting seat 5, a first flipping cylinder 7 on the handle 4, the piston of the first flipping cylinder 7 being hinged to the rotating base 6, and a second flipping cylinder 9 on the lifting rod 1, the piston of the second flipping cylinder 9 being hinged to the rotating base 6. The operation of the first flipping cylinder 7 causes the handle 4 and the rotating base 6 to rotate relative to each other, thereby causing the handle 4 to rotate relative to the rear door clamped on the fixing frame 10. The operation of the second flipping cylinder 9 causes the lifting rod 1 and the rotating base 6 to rotate relative to each other, thereby causing the lifting rod 1 to rotate relative to the rear door clamped on the fixing frame 10. The flipping operation of the rear door clamped on the fixing frame 10 is achieved through the first flipping cylinder 7 and the second flipping cylinder 9, thereby facilitating the removal of the rear door from the clamp. Specifically, the rotating base 6 is L-shaped and welded to the connecting seat 5, while the other end of the rotating base 6 is hinged to the pistons of the first flipping cylinder 7 and the second flipping cylinder 9.

[0026] Reference Figure 1 Both the boom 1 and the handle 4 are provided with a first fixed seat 8.

[0027] The clamping assembly includes a side seat 16 connected to the fixed frame 10, a gripper 17 hinged to the side seat 16, a second fixed seat 18 on the fixed frame 10, and a clamping cylinder 19 on the fixed frame 10. The cylinder body of the clamping cylinder 19 is hinged to the second fixed seat 18, and the piston of the clamping cylinder 19 is hinged to the gripper 17. When the clamping cylinder 19 operates, the gripper 17 rotates on the second fixed seat 18, thereby engaging with the rear door and fixing the rear door on the fixed frame 10. Specifically, the side seat 16 is fixed to the end of the fixed frame 10 by U-bolts, the second fixed seat 18 is connected to the fixed frame 10 by U-bolts, the second fixed seat 18 is connected to the cylinder body of the clamping cylinder 19 by a pin, the side seat 16 is connected to the gripper 17 by a pin, and the piston of the clamping cylinder 19 is connected to the gripper 17 by a pin.

[0028] One end of the mounting bracket 10 is provided with a first clamping seat 11, on which a first positioning block 12 is provided to contact the vehicle door. The other end of the mounting bracket 10 is provided with a cross post 13, on which a second clamping seat 14 is provided, and on which a second positioning block 15 is provided. The first positioning block 12 and the second positioning block 15 abut against the tailgate, thereby facilitating the gripper 17 to clamp the tailgate onto the mounting bracket 10. Specifically, there is one first positioning block 12 and one second positioning block 15. There are two clamping seats. The first clamping seat 11 is located at the raised end of the fixed frame 10. The first clamping seat 11 is connected to the fixed frame 10 by U-bolts. The first positioning block 12 is connected to the first clamping seat 11 by bolts. The horizontal column 13 is connected to the second fixed seat 18 at the end of the fixed frame 10 by U-bolts. Two second clamping seats 14 are symmetrically provided at both ends of the horizontal column 13. The second clamping seats 14 are also connected to the horizontal column 13 by U-bolts. The second clamping seats 14 are connected to the second positioning block 15 by bolts.

[0029] The first positioning block 12 and the second positioning block 15 are both nylon blocks, which protect the tailgate and prevent it from being damaged when it moves.

[0030] Both the boom 1 and the handle 4 are equipped with pneumatic control boxes 20. The pneumatic control boxes 20 control the first tilting cylinder 7 and the second tilting cylinder 9 respectively, thereby controlling the tilting of the rear door clamped on the fixed frame 10.

[0031] The handle 4 is provided with a first control arm 21, and the boom 1 is provided with a second control arm 22.

The pneumatic control box 20 is controlled by the buttons, thereby controlling the first tilting cylinder 7 and the second tilting cylinder 9. Specifically, both the first control arm 21 and the second control arm 22 are U-shaped, and both the first control arm 21 and the second control arm 22 face away from the clamping assembly, so that the control panel 23 on the first control arm 21 and the second control arm 22 can be conveniently controlled.

[0032] The boom 1 is equipped with a lifting column 2, and the lifting column 2 is equipped with a hook 3. The hook 3 is connected to an electric hoist, thereby lifting and moving the boom 1 and the entire device. Specifically, the lifting column 2 is connected to the boom 1 by U-bolts, and the hook 3 is connected to the lifting column 2 by U-bolts.

[0033] In summary, when it is necessary to move the rear door on the clamp, the lifting device is moved onto the clamp by the electric hoist. At this time, the first positioning block 12 and the second positioning block 15 on the fixed frame 10 abut against the rear door. At this time, the clamping cylinder 19 works to make the gripper 17 rotate on the second fixed seat 18, so that the gripper 17 engages with the rear door, thereby fixing the rear door on the fixed frame 10. Press the control button on the control panel 23 on the first control arm 21 and the second control arm 22 to control the pneumatic control box 20, thereby controlling the first tilting cylinder 7 and the second tilting cylinder 9. The first tilting cylinder 7 and the second tilting cylinder 9 work to make the rotating seat 6, the connecting seat 5 and the fixed frame 10 tilt, so that the rear door clamped on the fixed frame 10 can be tilted and removed from the clamp, thus facilitating the electric hoist to realize the transfer of the entire lifting device.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
